2 Government/IndustryMeeting February 5, 2009
Background
Industry petitioned the Agency to include the WorldSID 50th in Part 572 and FMVSS 214
the ISO biofidelity ranking system (ISO 9790) indicates that the WorldSID biofidelity is superior to ES-2reglobal harmonization
-
3 Government/IndustryMeeting February 5, 2009
Background (cont.)
A collaborative project evaluating an improved WorldSID has been completed
NHTSA worked closely with the WorldSID Task Group using 2 dummies provided by OSRPseveral improvements were made to the dummy during the evaluation
-
4 Government/IndustryMeeting February 5, 2009
Objectives
Present the results of the WorldSID and ES-2re biofidelity rankings using an updated version of the NHTSA Biofidelity Ranking System (H. Rhule, 2002 Stapp)
Share our observations relating to dummy design and performance
